IP or MAC, which one takes precedence in rules

When we build a definition using MAC(and IP as UTM doesn't allow mac-only rules), which value takes precedence?.

for example:
i have rule A from X station blocking everything.
then Rule B from Y (ip only) allowing only a certain URL.
then rule C from Z (ip/mac), allowing everything.

what happens when/if station X changes IP to the one that Y has/had and then Z?
theoretically it should keep triggering only the "X" rule as the MAC is unchanged, but that happens in Y case where it has only been defined as an IP host?, will it trigger both rules erroneously?

  •  i mean, if i use a host w/MAC definition is so that i can make mac-based rules regardless of wheter the user changes the ip to bypass rules.

    The way to always block a specific PC is with a Firewall rule like

    Internal (Network) -> Any -> Any : MAC=aa:bb:cc[:D]d:ee:ff : Drop
